1. An apparatus, comprising:
a front frame;
a temple arm;
a hinge rotatably connecting the front frame and the temple arm;
the temple arm comprising a circuit assembly including at least a radio that supports wireless communication;
the front frame comprising one or more antennas traces, wherein the hinge conductively connects the circuit assembly to the one or more antenna traces; and
an antenna tuner located between the circuit assembly and the hinge;
wherein a rotation position of the temple arm is sensed, wherein the rotation position is dependent on an orientation of the front frame relative to the temple arm; and
wherein the antenna tuner includes an impedance tuner to adaptively adjust an input impedance of the impedance tuner based on the sensed rotation position of temple arm.
